Switch-case with enum

Question

Can you use switch-case with an enum in Unity? If so, how do you format the conditional check?

FYI, the snippet below does NOT work (with ""'s around the conditional check, I get the cannot == error, as the enum is not a string) . As it is, I get the unknown identifier error.

enum choices{ APPLE, banana, canaple } function Start(){

var choice:choices=APPLE; switch(choice){ case APPLE: Debug.Log("APPLE"); break;

case banana: Debug.Log("B"); break;

case canaple: Debug.Log("CC"); break;

default: Debug.Log("nothing"); break; }

}

Yes, you can. Just modifying your code a bit :)

enum choices { APPLE, BANANA, CANAPLE }

function Start() { var choice : choices = choices.APPLE;

 switch(choice)
 {
     case choices.APPLE: 
         Debug.Log("APPLE");
         break;
     case choices.BANANA:
         Debug.Log("BANANA");
         break;
     case choices.CANAPLE:
         Debug.Log("CANAPLE");
         break;
     default:
         Debug.Log("NOTHING");
         break;
 }

}
